3D-printed animated pixel lamp

About this tutorial

Heliox designs a lamp shaped like a column of pixels: 128 addressable RGB LEDs, housed in a 3D-printed tower, are driven by an Arduino. One knob sets the brightness, the other switches animations. She shares the print files, the code and the wiring diagram.

What you need

• Arduino Mega
• 5 m of addressable RGB LEDs (33 mm spacing)
• 5 V power supply, at least 4 A
• 2 potentiometers, 220 Ω resistor and 470 µF capacitor
• Jack connector, wires and perfboard
• 3D-printed parts
• Soldering iron, hot glue and superglue
